Figure 3-15: Communication During DTMF Command
Launch Browser
This is a proactive command that requests a browser inside a browser-enabled user terminal to
interpret the content corresponding to a URL. It is forwarded to the TE using an unsolicited event
mechanism.
The TE answers this unsolicited response using the +MTKP command. For the general result,
"launch browser generic error code", the G24 must provide additional information.
